According to Aristotle, friendship comes in three forms. In the friendship of utility, ‘friends’ are friends because they benefit each other. Friendships of pleasure are those where individuals seek out each other’s company because of the joy it brings. The third category, friendship of the good, is based upon mutual respect, admiration for each other’s virtues, and a strong desire to aid and assist the other person because one recognises their essential goodness. Friendships of utility and pleasure are much less intense and less permanent. The same is the story of marriages. Marriages are a form of friendship.
